FR-ICTIONAL TRANSMKSSIQN MECHANISM.

To'all whom it ma 5; concern: Be it known that l. Brnox J. CARTER, a

troit, in the county of Wayne, State 0t" Michigan, have invented certain new and useful Improvements in Frictional Transmission Mechanism; and I do declare the. following to be a full, clear, and exact description of the HlYQIItiOD, such as will enalc-Z'e others skilled in the art to which it uppertains to make and use the same, reference being had to the accompanying drawings, and tothe figures of reference marked thereon, which. form a par of this specificution.

This invention relates to frictional transmission mechauisni. more especially designed for use in the propulsion or motor vehicles, and consists in the constrmiion and arrangement of parts hereinafter fully setforth and pointed out purticuiurly in, the claims.

The objectof the invention is to provide simple and etlieient means for transmitting the power from the motor shaft to the driven shaft in an economical manner, and in providing for a movement of the frictional transmitting disk to enable it to he aupiieal with the requisite. pressure againsttl-e friction wheel on the driven shaft, the driven shaft being provided with means for maintaining it parallel with the face of the tmnsmitting disk and the friction when on said shut t lining rendered readily movable across the face of said disk.

The above object is attained hf. the structure illustrated in the accompanying draw ing, in which:-

Figure 1 is a side elevation of the frame of a motor .vchicle, partly in section, showing the application of my invention. Fig. 2 :1 plan view of the chassis of a motor Vehicle, showing my transniision mechanismnzounted therein. Fig. 3 is on enlarged Fig. 4 is an enlarged fragmentary view, showing the telescopic motor shaft, the transmitting disk on the end thereof, thr' bull thrust. hearing at the rear of said disk and the shaft. hearing through which" the motor shaftslirles longitudinally, together i with the means for sliding said shaft.

connected and upon said shaft adjacentto the motor is the usual fly Wheel 7. The

motor shaft is made telescopic by means of the sleeve 8 which is fixed to the longitudinally movable section thereof {see Fig. 4;) and which extends onto and embraces, as at 9. the section of the motor shzrit which is connected directly 'ith the ntotor, thereby permitting u longitudinal reciprocation of that portion of shaft 4 which carries the transn'iirting disk 5. pling the sections of the motor shaftin a. manner to allow one portion thereof to reciprocate longitudinally as well as rotate, the sleeve 8 is provided with the laterally extending arms 10 having eyes 11 at; their extremiti s through which pass the pins 12 which are seated in the web or spokes 13 of the fly wheel and receive on theirinner ends the nuts l4... each of said pins having a To provide for coushoulder or col ar 15 thereon which engages the wet) or spokes of the tly wheel; Mounted upon each of rue pins 12 between the eye 11 of the arm. 10 and the collar 16 secured to the curl of said pin, is a coiled spring l1 who e tension normally exerted to hold the eyes 11 ofthe arms 10 against the collars 15 of the pins 12. The opposite end of the motor sha ft is supported in a bearing box 18 suitably secured to the frame within which is a slidable non-rotative sleeve 19 through which said shaft. passes and in which it. rotates. On the outer end of said sleeve is a ball cup 20 having therein a race .way 21 in which are located the bearing in the inner end of the sleeve 19 is a, yoke i l i l i i 2 i or ring 24 having the projecting pins 25 on which are jc-urnaled the antifriction rollers 26. Fulcrumed on pins 27 mounted in the frame of the bearing 18 are the forks of the bifurcated eccentric lever 28 which bear against said antifriction rollers, the lower end of said lever being attached to the connecting rod 25) that leads to the foot lever 30. By operating said lever, the rod 29 will be drawn upon to carry the ends of the forks of the eccentric lever against the antifriction rollers 26 and move the sleeve 19 longitudinally. causing said sleeve to sl1(le through the bearing 18 and carry with It the shaft a by means of the thrust hearing before described, whereby the disk 5 is caused to move into forcible contact with the peripherj. of the wheel 3. To accommodate said longitudinal movement of the forward section of the driving shaft. the springs 17 contract and the sleeve 9 slides over the motor section 45 of said shaft, as shown by dotted lines in Fig. 4. Upon the release of the foot lever, the springs 17 will retract section 4, of the motor shaft and withdraw the transmitting disk from. engagement with the periphery of the wheel The. power exerted through the eccentric levers 28 and the foot lever 30 enables the transmitting disk to be carried tl, S nicient force against the wheel 3 to prevent slipping.

To slide the wheel 3 upon thc driven shaft across the face of the disk 4, a bell crank lever 31 is employed, the longer end of which engages in a suitable manner the hub of Wheel 3 and the shorter end of which is coupled to one end of a connecting rod 32 whose opposite end is attached to a crank 33 on a rock shaft. 34 adapted to be actuated by a le er 35. Through the operation of said lover the wheel 3 may be carried across the face of the disk to vaiy the speed of the driven shaft, or reverse the iirection of rotation thereof, as shown by dotted lines in Fig. 2. Upon the driven shaft is a sprocket wheel 30 connected by a sprocket chain with the differential gear 37 on the rear axle 38.

The bearing boxes 39 which support the ends of the shaft 2 are made laterally adjustable by means of the adjusting screws 40 which engagesthe opposite ends thereof, whereby said shaft may be brought into parallel relation with the face of the disk As the arrangement for adjusting the bearing boxes 39 is more clearly set forth m a companion application executed on even date herewith, such structure need not be more fully set forth herein.

Having thus fully set forth my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a transmission mechanism, the combination of a sectional motor shaft, a wheel -thereon, guide pins extending from said wheel, a section of the motor shaft being longitudinally movable, a sleeve upon said .movable section embracing the end of the other portion of the shaft to maintain said sections in alinement. lateral arms projecting from the longitudinally movable portion of the shaft through which said pins pass and which are slidable upon said pins, 8. spring upon each of the pins confined between the end thereof and said slidahle arm, and means for sliding the longitudinally movable portion of said shaft against the action of said springs.

' 2, In a transmission mechanism, the tornbination of a motor shaft formed of two sections, one of which is longitudinally movable, a telescopic joint connecting said sections, :1 spring for returning the longitudinally movable section ofthe shaft after being extended. a collar embracing the shaft within which the shaft rotates, said collar having projections thereon, eccentric levers engaging said projections and having fixed fulcrums, and means for actuating "'iid eccentric levers.

In a transmission mechanism. the combination ofa motor shaft formed in two srctions,-a number upon the non-slidable movable, a telescopic point connectin said sectiones, a member upon the non-slidable v portion of said shaft having projectin pins which lie parallel with the axis 0 said shaft, radial arms on the slidable'portion of said shaft having a slidable engagement with said pins, springs upon said pins interposed between the ends thereof and said arms on the slidable portion of said shaft,

and means for moving the slidablesectiou' of said shaft against the action of said springs,

5. In a transmission mechanism, the combination of a sectional motor shaft, one section of which is longitudinally slidablo, a member upon the non-slidable portion of said shaft, pins projecting from said member parallel with the axis, of said shaft, I.
